The sum of two numbers is 86, and their difference is 20. find the two numbers

The difference between two numbers is one. three times the larger number minus two times the smaller number is 9. what are the two numbers

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
